Question

I\'m trying to create an Nginx/PHP FPM setup with docker compose and am having issues with the version 3 volumes syntax/changes.

My Dockerfile:

Answer 1

For using "Named volumes" for sharing files between containers you need to define

1) volumes: section on the top level of yml file and define volume name

volumes:
  php:

2) define volume section on first container like you did (Where share will mount)

web:
    volumes:
      - php:/var/www/html #<container_name>:<mount_point>

3) define volume section on second container (Share will mount from)

php:
  volumes:
    - php:/var/www/html

4) (optionally) If you need to store volume data on the host machine you can use local-persist docker plugin. You can specify docker volume driver and path where you data will be stored.

volumes:
  php:
    driver: local-persist
    driver_opts:
      mountpoint: /path/on/host/machine/

In your case you forgot define volume name for php container. Just replace

  php:
    build: .
    volumes:
      - ./html:/var/www/html

to

  php:
    build: .
    volumes:
      - php:/var/www/html

and use Local Persist Docker Plugin
